1. Noise:
Turns our Fender in their infinite wisdom of R&D decided the PJ doesn't need the green heater wires twisted together and routed separated from signal wires in the chassis like every other amp on the planet. In fact, they're run un-twisted, in parallel and zip tied tightly to both power and signal wires. Duh, Fender. I started by cutting the zip ties and moving the rest of the wires away and laying those wires close to the PCB and front of the chassis. Then, holding the heater wires apart (still attached on both ends) I started twisting the pair together at both ends working my way to the center. Then I routed them first from the lower tube socket PCB along the rear edge of the chassis, crossing other wires at right angles and keeping them toward the rear panel (or where it will be when buttoned up) to the power transformer. I then pushed the other wires together and tucked toward the top of the chassis but didn't zip tie anything together. I powered the amp up and it's not dead silent, but at least 90% better than it was stock. |
